Ok, where to start? I went to the dyno two weeks ago to tune my car for an autocross. I had no number's in mind for making power, I just wanted a tune. Logan at Defined Autoworks built and tuned this car, here is what happened. We did many pulls with these numbers and checked the dyno, its a dynapak as well. We also only had 93 in the car it has been running 93 since. I had a dirty k&N on the car, the whole time (4in). I also had 2 year old plugs in the car from my work bench. No nos, no tricks just whats here.

Here is the car, a rotary powered s14 beast



peak power ( you can see the spike to 16 pounds then it holds 14 pounds to redline)



peak torque




We were stunned, I don't think there has been a 2 rotor with just a half bridge and regular old 35r make this power. I will provide more detailed specs further down. The 35r is just a dual bb precision, NOT a billet wheel.

Here are the engine specs

13b-rew block and irons
13b-re port runners
D.A circuit port on the primaries
D.A half bridge on secondaries
D.A turbo exhaust port
Fd 9.0:1 rotors, balanced and clearanced.
3mm Apex seals
solid corner seals
New FC rotor housings
Coolant jacket modifications
race rotor bearings
high pressure oil reg
FC front cover
13b-re intake manifold

Turbo

1.00 divided turbine
p-trim wheel, standard wheel
.70 compressor housing

Electromotive Tec GT
Inductive coils
S4 Fc waterpump
Racing beat front pulley
Mazda comp waterpump pulley

We are going to go back with race gas and play with the timing, the timing is conservative. I will update the thread with the new results. I will also post engine pics if they must be had, I just don't have any on hand.

so uh do people give you crap about swapping a rotary into an s14 chassis?

Run the car up on a dyno dynamics dyno and see what it makes with no correction

got any pics of the engine bay?

People don't really give me any crap in real life. The car is built to perform on a track, so when it does that what can they say? On the forms you always get the hatters, people hated on my FD. I don't think it can be escaped. I always explain the advantage i get from a lighter car from what my FD was. The full cage eliminates the disadvantage the s14 has in chassis rigidity. The s14 also has a horrible weight distribution with any nissan engine compared to an FD. The rotary makes the weight distribution better in an s14 than an FD. The gas tank is also in front of the rear axle on an s14, compared to an FD which is located as far back as possible. The only thing you can't change on an s14 is the macpherson strut. I honestly don't notice any difference. I have ran 3 seasons with my FD since I had it. I have only ran 2 events with my s14. My s14 is far more capable than my FD was, it is way more stable to me. I know people will probably argue with me on this. Im just stating what I noticed from car to car. My FD also had the same coils, and was built very similar to this car.

The correction just corrects for different conditions, so some one in a different area wont have an advantage due to conditions. If I ran the car with no correction right now it would make more power because it's like 40 fahrenheit here, with dry air. I believe that's what correction is for on a dyno. Also the only dyno we have access to around here are dyno-jet, mustang dyno, and dynapak. The dynapak is the lowest reading dyno we have used, and seems to give the most accurate numbers. We had a 40hp difference on an fc from the dynapak to a mustang dyno. The fc was a 360whp car on the dynapak and made 400 on a mustang dyno.

I will post up pics of the engine bay today.

Engine bay pics. The engine placement is excellent in the chassis. The front of the engine is even with the shock towers. The top of the block is about half way up on the towers. The intake is pretty tall so it looks like the engine sits high. The engine was initially designed to use a dry sump system, so the bottom of the block basically sits on the subframe. The subframe was modified and a custom oil pan was built by defined instead of using a dry sump. The placement of the engine did not have to move due to subframe modification. Everything was built by defined. The car was at Gordon's meet two years ago.

Im bad at taking pics, but you get the idea.

RXS14! Very Nice. Any vids? I think it's schweet!

Seems reasonable, your running 13B RE port work with a P-trim turbine on a 1.0 housing. If it's a 61mm compressor it's very similar to the 3574 and not a 35R difference being a 65mm exducer versus 62mm. We make mid 400's with those around 17psi all day with a .84 housing and smaller port work. Good numbers though I bet that car is a riot to drive. I'd certainly show it off.

congrats awsome ride..
putting a rotary in anything should be a good thing haters are just jelous cause they dont have the skill to pull off a project.

Paying back the Nissan guys one rotary engine at a time. Props to Defined on a well-built car.

very very nice setup. what boost were you running to make that hp?

Screw what people say and whatever numbers you might put down.

the part i have a hard time believing is 375 ft lbs for such low boost. the torque just kept rising thoughout the band. it looks to be 16 lbs in the begining but looks to climb to 20 psi or so. either way thats a great number.

No we looked at everything while we were doing the pulls. I do not have a boost controller either, I just run wastegate spring. My gate is also an HKS gt2 50mm. The spring is 15lbs. Im not sure my numbers have been made by any other 2 rotor with a 35r. I know Defined did not just stumble by these hp numbers. Logan and Peter have put tons of research and development into this engine. Logan's n/a 2 rotor I do believe holds the streetport record, which helped develop my engine.

Here is a burn-out vid. We were bored, in the middle of hick town usa, and one car a day goes down this road if your lucky. It's not much of a burnout but you can hear the spark cut only rev limiter.

Alot of people were wanting charts such as boost pressure, corrections etc. So here is pretty much everything I could think of that documents the results. Its still the highest 35r non-billet turbo 13b dyno chart backed by verified proof that I've seen posted. These numbers will be re-broken again I am sure on monday once we get back to the dyno again. But until then, enjoy!

First off is the charts showing TCF. And it of course is 1.00


Next up is the boost chart by itself


Then we have the boost chart and torque line to show relationships

very impressive for a p trim 35r or 61mm setup both tq and power. dont see many pump gas setups running that strong. what kind of timing are you running at 6000 rpms? car must be a blast to drive also.

GtoRx7.

iTrader: (12)

6000rpm..... 13 degrees @ 16psi

Opps, looked back through and see it was 13-14psi

so would be 14 degrees

The only thing I can use to describe how the car feels, it this video
